On cause of environmental pollution is the presence of heavy metals. Heavy metal such as Cd (II), Pb (II) and Cu (II) are the metals commonly found in water pollution. The untapped shell of ketapang fruit can be used as an absorbent because it has an active side that can bind to the metal ion. From the research with batch sistem was found that the absorption efficiency of metal Cd (II), Pb (II) and Cu (II) by shell of ketapang will be optimum if done at pH 6 with contact time 60 minute for ion Cd(II), 45 minute for ion Pb (II) and 75 minute for ion Cu. The optimum stirring speed of each is 100 rpm, 150 rpm and 100 rpm. The optimum absorption efficiency occured at concentration of 10 mg/L on metal Cd (II) and Pb (II) that are 86,38 % and 98,...
